Specification of Letters Patent.

Patented Feb. 3, 1920.

Application filed July 19, 1919. Serial No. 312,011.-

To all whom it may concern:

Be it known that I, WILLIAM H. GERHARD,

a citizen of the United States, residing at Austin, in the county of Travis and State of Texas, have invented a new and useful -Tobaco-Pipe, of which the follovvlng 1s a specification.

This invention relates to tobacco plpes,

. and the object'is to provide a pipe having the outward appearance of an ordinary pipe, and yet embodying advantageous features not foundin the latter, said features, to be later enumerated, being incorporated within the improved pipe in a manner to obviate the necessity for unsightly protuberances, or other objectionable or freak formations, which are not desirable to the confirmed smoker.

The principal object is to provide in a pipe of this character means for trapping the nicotin while permitting of free passage of the smoke from the bowl of the pipe to the mouth of the smoker, the said means being carried wholly by the bit of the pipe, which may be readily removed from the said bowl for the purpose of cleansing the smoke passage, or for replenishing absorbent material, which may be utilized within the trap and otherwise cleansing the latter.

Further objects are to so arrange the trap as to catch and hold saliva gravitating down the bore of the bit, and to prevent the same from again reaching the mouth of the smoker even though the pipe should be tilted or turned at any angle, and to accomplish these objects with a minimum number of parts which may be assembled for the purpose without the necessity of any nicety of adjustment, or without any possibillty of derangement.

A full and complete understanding of the invention may be obtained from a consideration of the following detailed description, taken in connection with the accompanying drawing forming a part of this specification; it being understood that while the latter shows a practical form of the invention, the latter is not confined to strict conformity therewith, but may be changed or modified, so long as such changes or modifications mark no material departure from the salient features of the invention, as specifically pointed out in the appended claim.

In the drawing, wherein similar reference characters designate corresponding parts throughout the several figures Figure 1 is a longitudinal sectional view through a-pipe of a well-known pattern and having the improvements embodied therein.

Fig. 2 is a similar view of the bit removed from the stem of the pipe.

Fig. 3 is a sectional line 3 -,3 of Fig. 1.

Fig. 4 is adetail perspective view of the absorbent material removed from the trap.

Many devices of more or less complicated nature have been incorporated in tobacco pipes for accomplishing the purposes sought herein, and placed upon the market without success for the very reason of their multiplicity of parts, which easily become deranged and require accurate adjustment to secure registration of co-acting ducts, passages, etc., in order to secure the best results, whereas the device of the present invention is so designed as to perform the necessary functions by merely inserting the bit within the stem of the pipe in the usual position, as in ordinary pipes and forcing the same therein to secure the customary frictional engagement for holding the partstogether.

lVhile the pipe illustrated in the drawing is of the well-known lVellington style, it is to be understood that the invention may be equally as well applied to other styles of pipes and the proper functioning of the parts obtained.

In the drawing 1 indicates the bowl of,

the pipe having the usual obliquely arranged integral stem 2 provided with a tapering bore 3 longitudinally thereof and extending substantially half the length of the said stem 2. A smoke duct 4 connects the bottom of the tobacco receptacle 5 of the bowl 1 and, inclining upwardly joins the inner end .of the bore 3, at the upper side thereof. The usual ferrule 6 surrounds the outer end of the stem 2 for the purpose of strengthening the same,

view, taken on the The removable bit 7, which may be made of any of the materials used for this purpose. is of the common curved type provlded with the smoke passage 8. arranged centrally of the said bit. which is provided intermediate its length with the usual annular enlargement 9 adapted, when the bit is in position within the stem '2, to lie adjacent to the ferrule 6 and to provide a gradually tapering shoulder for frictionally engaging the outer end of the bore or socket 3. The inner end of the bit is tapered to a greater degree than the surrounding bore or socket 3, which thus provides between the two parts a space 9. gradually increasing in area toward the inner end of the said bore.

This surrounding pace 9, which has free communication with the bowl of the pipe through the duct l, acts to cool the smoke somewhat before entering the passageway 8 on its way to the mouth of the smoker. The bit below the annular enlargement has a slightly tangential branch passage 10, which forms a reduced continuation of the smoke passage and terminates in an inlet opening 11. which i thus located well beyond the point where the bit frictionally engages the outer extremity of the bore of the stem 2, and always in a position to communicate with the surrounding space 9, for the purpose of receiving the smoke from the bowl no matter what position the bit 7 may assume with relation to the said bowl. It will be seen that no nicety of adjustment is necessary when placing the bit in the socket of the pipe stem for the purpose of securing the necessary communication with the bowl of the pipe.

At the inner. enlarged end of the bit, there is provided a central longitudinally dis-' posed chamber 12 having its outer end curved, as indicated at 13, to conform to the curvature provided by the enlargement 9 and extending to the inner end of the bit and constituting a trap for nicotin and saliva in a manner to be explained. The smoke passageway 8 communicates with the interior of the trap or chamber 1:2 by a short ductll. which connects with the latter at a point where the curvature of the end portion 13 starts. thus forming an inclined entrance opening into'the said trap, through which saliva may easily gravitate into the trap. but which will not again enter thesmoke passageway S no matter if the pipe be turned or tilted. It should be noted that the branch passage 10 is smaller in diameter than the smoke passage 8 and at its junction with the latter is spaced from the duct l-l by a partition 15. 1

At the inner end the bit is reduced and threaded at 15* for the reception of a screw cap 1 6. which has an exterior diameter conforming to the bit and which is adapted to be screwed thereon for closing the inner end of the chamber 12. In practice it has been found advantageous to insert a small roll of blotting paper 17, orsome other absorbent material into the trap for the purpose of absorbing the nicotin'and saliva which may enter the same, as the said roll may be conveniently placed in position therein and removed from the same, after the bit has been detached from the bowl of the pipe and the cap 16 unscrewed, without soiling the hands of the smoker.

hen the bit 7 is inserted in the socket of the pipe stem 2, as illustrated in Fig. 1 of the drawing. and which is the ordinary position in pipes of this character, it will be readily seen that, when the smoker draws upon the passageway through the bit the smoke from the tobacco receptacle 5 will pass through the. duct l and enter the surrounding space 9 where it will be partially cooled and thence through the branch 10 into the passageway 8 to the mouth of the smoker without being in any degree deflected. At the same timesaliva entering the passageway from the mouth of the smoker will gravitate down the passageway 8, through the short duct H and into the trap 12,- the said duct ll being located beneath the smoke inlet 10, so that such saliva is efl'ectually prevented from reaching the smoke duct l and t1 us entering the bowl of the pipe. It will further be seen that by removing the bit from the bowl and then unscrewing the cap and taking out the roll of absorbent material, the chamber or trap may be readily cleansed and a straw or Wire readily introduced through the short duct ll and the passageway 8 to freethe same from any particles of tobacco which may have lodged therein. and that the tangential branch 10 constituting the smoke inlet may likewise be freed from such particles by in troducing a cleaner through the opening 11 and pushing the same backward through the passa eway 8.

From tie foregoing it will be seen that an extremely simple construction has been provided whereby the nicotin and saliva is effectively trapped, that the pipe may be easily and quickly cleaned and that the bit may be placed in the stem of the pipe without special care being taken to have the parts function properly.
